A bill in the California legislature (AB 2773) that would open up the wider use of renewable natural gas (RNG) in alternative fuel vehicles moved out of its first committee in the lower house Assembly earlier this month.

The bill would eliminate current roadblocks to transporting RNG in natural gas pipelines.

RNG, or biomethane, can allow for a cleaner version of compressed natural gas (CNG) or liquefied natural gas (LNG) to be used increasingly by fleet operators (see Daily GPI, March 30), but most RNG produced in California has to be used onsite for electric generation because of existing restrictions on the co-mingling of biomethane with natural gas in the state's pipeline infrastructure. AB 2273 seeks to change that.
